Add /usr/java/bin to your path in your file ~/.bash_profile.

Code:

vim ~/.bash_profile

Mohama: you missed part of the instructions:

Quote:

Add /usr/java/bin to your path in your file ~/.bash_profile

Your PATH is setup in your .bash_profile file.

Edit this file: ~/.bash_profile

Look for a row that says "PATH=".

Go to the end of this line and add ":/usr/java/..." (whatever your path to Java is) - Note: Dont forget the colon to separate the new path from the existing ones.

Save and exit.

Open a new shell window and try just saying:

"> javac <program name>"

Your old window WILL NOT work this way unless you do the ~/.bash_profile instruction that mrcheeks said.

Does this make sense?

VIM is just another text editor among others...

According to my book Core Java2 to set your classpath do the following

export CLASSPATH=

mohama,

Instead of adding ":/usr/java/jdk1.5.0_03/bin/javac" to your path, just add ":/usr/java/jdk1.5.0_03/bin". This will look in that folder for the "javac" executable whenever you type "javac" on the command line.

try logging out & logging in again

or open a new shell
